Barry Grant/Quik Fuel/Holley interchangeables

After declaring bankruptcey in 09 Barry Grant/Demon shutdown operations as of yesterday. The question is other than main jets and gaskets what other "internal" parts are interchangeable between the 3 Carbs. This is a legitimate question as some of our younger members might not know the answers so lets keep it clean and leave things like personel preferences out of the discussion please and thankyou.
